System and method for blocking phishing attempts in computer networks

A system for blocking phishing attempts in a computer network with at least one gateway server, the system comprising:

• a processor, in communication with the at least one gateway server, wherein the processor is configured to:
• receive a list of assets of the computer network, wherein each asset is associated with at least one computer network address;
• generate at least one address permutation on the at least one computer network address of each asset of the computer network, wherein the generated at least one address permutation is different from the address associated with each asset of the computer network;
• receive a communication request at the gateway server;
• determine a destination address of the communication request;
• compare the determined destination address with the at least one address permutation;
• and
• when the determined destination address is the same as at least one address permutation, block the communication request at the gateway server.

A method of determining phishing attempts in a computer network, the method comprising:

• receiving, by a processor, a list of assets of the computer network, wherein each asset is associated with at least one computer network address;
• generating, by the processor, at least one address permutation on the at least one computer network address of each asset of the computer network, wherein the generated at least one address permutation is different from the address associated with each asset of the computer network;
• receiving, by the processor, a communication request at a gateway server of the computer network;
• determining, by the processor, a destination address of the communication request;
• obtaining at least one IP address corresponding to the generated at least one address permutation;
• and
• when the obtained at least one IP address is associated with a phishing address, determining that the destination address is associated with a phishing address.
